You must add as much oil as you took out when replacing parts, making sure the new oil works right with the R-134a system. You must replace the receiver-drier when you change the condenser. Plume first has the refrigerant taken out of the air conditioner and put away through an A/C professional. Take out the power cable from its connection to the car's battery negative end. Take the coolant reservoir off and put it aside without taking apart the hose linking it to the radiator. When the car uses an automatic transmission, take out the transaxle oil cooler before starting work. Remove the bolts holding the brackets for the radiator, then disconnect the two refrigerant lines next to the right side of the radiator. After loosing the lines, pull the radiator slightly back. Free the condenser by loosening the mounting bolts, then unclip its lower legs from their supports. Raise the condenser straight up and remove it. Before using the old condenser again, run a fin comb along its bent fins to straighten them, while wearing goggles and eye protection and blowing compressed air through to remove debris. You reassemble everything back together when installing, connecting new O-rings that come with lubricant from the R-134a refrigerant oil, and always use O-rings meant for AC systems. When you replace the condenser, put in 2/3 ounces (20 milliliters) of fresh oil for keeping the system running smoothly. After connecting the battery, send the discharged system to the shop for evacuation, charging, and leak testing.
